I agree with rubber duckie. In a pre season friendly players have to make judgements about how much they put their bodies on the line.
No doubt later in the season we will have some debate about whether it's better to 'peak at the right time' like Wigan/Leeds do, or to go all out every week to try to win the league leaders shield and risk burn out by the end.
But nobody will say "if only we'd had players putting their body on the line more in that pre season game we could have beaten Salford by a bigger margin".
However when duckie says that is a display of a championship winning team, he's getting a bit ahead of himself.
